Abstract
INTRODUCTION & AIMS Non Steroidal Anti-Inflammatory drugs (NSAIDs) are potent inhibitors of post-traumatic pain. Several studies have highlighted that NSAIDs could exert a negative effect on bone healing process possibly by down-regulating chondrogenesis and endochondral ossification. The aim of the study is to explore the potential mechanism though which NSAIDs can affect chondrogenesis. M&M: Trabecular bone from the fracture site was isolated from 10 patients suffering from long bone fractures. Mesenchymal Stem Cells (MSCs) were isolated following collagenase digestion and functional assays to assess the effect of diclofenac sodium on chondrogenesis were performed. Gene expression analysis of 84 key molecules was performed. RESULTS Diclofenac sodium inhibits chondrogenic differentiation and induces a strong inhibition of prostaglandin E-2 (PGE-2) production during chondrogenic differentiation. Replenishment of PGE-2 did not reverse this negative effect. Chondrogenic inhibition is similar in cells treated only for the first week of chondrogenic differentiation or continuously for 3 weeks. Gene analysis shows a strong downregulation of TGF-β3 and FGF-1 while TNF was upregulated. CONCLUSION NSAIDs seem to affect the transition phase of mesenchymal stem cells towards functional chondrocytes. This effect is unrelated to the endogenous production of PGE-2. The downregulation of the expression of key molecules like TGF-β3 seem to be the underlying mechanism.

Abstract
In the context of modern drug discovery, there is an obvious advantage to designing phenotypic bioassays based on human disease-relevant cells that express disease-relevant markers. The specific aim of the study was to develop a convenient and reliable method for screening compounds with Tumor Necrosis Factor-alpha (TNF-α) inhibitory activity. This assay was developed using cryopreserved ready-to-use cartilage-derived cells isolated from juvenile donors diagnosed with polydactyly. It has been demonstrated that all donor (10 donors) cells were able to respond to TNF-α treatment by increased secretion of pro-inflammatory cytokine IL-6 into subcultural medium. Inhibition of TNF-α using commercially available TNF-α inhibitor etanercept resulted in a dose-dependent decrease in IL-6 production which was measured by Enzyme-Linked Immunosorbent Assay (ELISA). TNF-α dependent IL-6 production was detected in the cells after both their prolonged cultivation in vitro (≥20 passages) and cryopreservation. This phenotypic bioassay based on ready-to-use primary human cells was developed for detection of novel TNF-α inhibitory compounds and profiling of biosimilar drugs.

Abstract
Rheumatoid arthritis (RA) is one of the inflammatory joint diseases that display features of articular cartilage destruction. The underlying disturbance results from immune dysregulation that directly and indirectly influence chondrocyte physiology. In the last years, significant evidence inferred from studies in vitro and in the animal model offered a more holistic vision of chondrocytes in RA. Chondrocytes, despite being one of injured cells in RA, also undergo molecular alterations to actively participate in inflammation and matrix destruction in the human rheumatoid joint. This review covers current knowledge about the specific cellular and biochemical mechanisms that account for the chondrocyte signatures of RA and its potential applications for diagnosis and prognosis in RA.

Abstract
Inflammation plays a major role in progression of rheumatoid arthritis, a disease treated with antagonists of tumor necrosis factor-alpha (TNF-α) and interleukin 1β (IL-1β). New in vitro testing systems are needed to evaluate efficacies of new anti-inflammatory biological drugs, ideally in a patient-specific manner. To address this need, we studied microspheroids containing 10,000 human osteoarthritic primary chondrocytes (OACs) or chondrogenically differentiated mesenchymal stem cells (MSCs), obtained from three donors. Hypothesizing that this system can recapitulate clinically observed effects of anti-inflammatory drugs, spheroids were exposed to TNF-α, IL-1β, or to supernatant containing secretome from activated macrophages (MCM). The anti-inflammatory efficacies of anti-TNF-α biologicals adalimumab, infliximab, and etanercept, and the anti-IL-1β agent anakinra were assessed in short-term microspheroid and long-term macrospheroid cultures (100,000 OACs). While gene and protein expressions were evaluated in microspheroids, diameters, amounts of DNA, glycosaminoglycans, and hydroxiproline were measured in macrospheroids. The tested drugs significantly decreased the inflammation induced by TNF-α or IL-1β. The differences in potency of anti-TNF-α biologicals at 24 h and 3 weeks after their addition to inflamed spheroids were comparable, showing high predictability of short-term cultures. Moreover, the data obtained with microspheroids grown from OACs and chondrogenically differentiated MSCs were comparable, suggesting that MSCs could be used for this type of in vitro testing. We propose that in vitro gene expression measured after the first 24 h in cultures of chondrogenically differentiated MSCs can be used to determine the functionality of anti-TNF-α drugs in personalized and preclinical studies. © 2018 American Institute of Chemical Engineers Biotechnol.

Abstract
In vitro cell-based models are important tools for assessing efficacies of new leads in early phases of drug development. Human osteoarthritic chondrocytes (OACs), obtained from biomedical waste material, represent a valuable, relatively accessible cellular source that could be used for this purpose. By employing reverse transcription-polymerase chain reaction (qRT-PCR) we compared gene expression profiles of key anabolic, catabolic and inflammatory genes of freshly isolated vs. monolayer cultured OACs (passages P0-P2) and non-stimulated vs. tumor necrosis factor alpha (TNF-α) stimulated P2 OACs. After expansion of OACs in monolayer cultures, the expression of almost all analyzed genes significantly decreased. The subsequent addition of TNF-α to OACs at P2 significantly increased expressions of all catabolic and inflammatory genes, leaving the anabolic profile almost unchanged. TNF-α-treated OACs were later utilized for efficacy testing of anti-TNF-α drugs infliximab and etanercept and both significantly reduced the expressions of all catabolic and inflammatory genes tested.
